A me è successo una cosa analoga, ho provato ad aggiornare da Roza 2.0.1V1 16 maggio a Rozak 2.0.1 V1 di aprile per il problema del Wifi che non rimane attivo in sleep anche se settato.
Ho utilizzato l'update.zip e installato da TWRP, l'aggiornamento non ha dato errori ma al riavvio non si accendeva e tornava in TWRP.
Ho risolto con Clean Install della 2.0.1 rozak di aprile.
Ho seguito questa procedura che penso vada bene anche per te
segui tutti i passi come indicato:
ONDA_V975m_V1_v2.0.1_rozak_20140516 - Onda Tablet Forum
Case B - Clean install
Follow these steps exactly:
1- Extract the .rar file of the ROM. You will get these files:
aml_autoscript
factory_update_param.aml
recovery.img
u-boot.bin
update.zip
2- Put an SD card of size up to 16GB in card reader.
3- Format the SD card with SDFormatter version 4 (hint: run this program as administrator).
You can download it from here:
SD Formatter 4.0 for SD/SDHC/SDXC - Tools for Onda v975m - Onda Tablet Forum
4- Make the SD card bootable with SDcardMaker_uboot tool.
You can download it from here:
SD Card Maker - Tools for Onda v975m - Onda Tablet Forum
IMPORTANT: Select the u-boot.bin from the ROM you extracted in step 1.
Format the card when asked to by the SDcardMaker_uboot. Format must be FAT32 with 32KB cluster size.
5- Copy all the files you extracted in step 1 to SD card.
6- Safely remove the SD card from the computer (Very important!).
7- Power off the tablet by pressing <Power> button for 20 seconds.
8- Put the SD card into the tablet's card slot.
9- Press simultaneously AND HOLD the buttons <Power> and <Volume +>.
10- When the green droid appears (or after about 5 seconds if no droid appears) release ONLY <Power> button. Keep pressing <Volume+>.
11- After about 1-3 minutes you will see the big droid with the spinning cube. Now release the <Volume+> button.
12- When the update finishes, the tablet will reboot. As soon as you see the ONDA logo, you are in business.
